2 Chelonian Taxonomy Order: Chelonia/Testudines 2 Suborders: 1.Pleurodira ( 2 families, approx. 75 spp.) Side-neck turtles: unable to retract neck Aquatic – semi aquatic 2.Cryptodira ( 11 families, approx. 200 spp.) Able to retract neck straight back into shell Terrestrial, aquatic, and semi-aquatic

20 Nutrition: Water Always provide fresh water! Water bowls Misting leaves and rocks Soak terrestrial chelonians daily Dehydration, gout, renal disease

21 Nutrition: Feeding Herbivores ~ 95% vegetables Mustard & collard greens, dandelions, kale, parsley, watercress ~ 5% fruit Grapes, apples, tomatoes, mangos, stawberries Need vitamin & mineral supplements Blend together!

22 Nutrition: Feeding Omnivores 50% animal/high protein foods Earthworms, crickets, slugs, snails, pinkies 50% plant material 75% vegetables -Lettuces, kale, carrots, sweet potato, alfalfa 25% fruit -apple, orange, banana,

23 Nutrition: Feeding Carnivores Turtles: Whole fish, rats, mice & pinkies, shrimp (w/shells) Insects in moderation

24 Nutrition: Feeding Frequencies Most tortoises: Every other day Aquatic/Semi-Aquatic chelonians: 2-3x a week Large carnivorous: Alligator Snapping Turtle 1- 2 times a week

25 Resume Husbandry for Reptiles Understanding the natural history (anatomy, physiology, habitat requirements, reproductive habits, behavior, longevity) of the patient in question is the greatest diagnostic tool in differentiate between normal health and disease. Combining this knowledge with the presenting complaint, medical history, physical examination and laboratory data is necessary for the treatment and rehabilitation of the diseased patient.
